Abstract

A fan gear drive system includes a torque frame (56) having a base (61) with integrated gear shafts (58) circumferentially spaced relative to one another. A fan shaft (34) is integrated with the base (61), such that the torque frame (56) provides rotational output from the fan gear drive system. Each shaft provides a shaft axis. A bearing assembly (60) is mounted on each of the gear shafts (58). The bearing assembly includes a spherical bearing (88) configured to permit angular movement of the bearing axis relative to the shaft axis.
